Gravity: DHT22 Temperature and Humidity Sensor

DHT22 is a capacitive humidity sensing digital temperature and humidity module with calibrated digital signal output. Using dedicated tech, it has high reliability/stability, including a capacitive wet component, high-precision temp device, and 8-bit MCU. Features: excellent quality, fast response, strong anti-jamming, cost-effectiveness, standard single-bus interface, small size, low power, 20m transmission. Higher precision, replaces SHT10, measures env temp/humidity, and works with Arduino for interactive effects.
